We found that CCL2, C-C motif chemokine ligand 7 (CCL7), C-C motif chemokine ligand 3 (CCL3), CXCL1, C-X-C motif chemokine ligand 2, C-X-C motif chemokine ligand 3, C-X-C motif chemokine ligand 5, IL-6, IL-19, IL-27, and IL-33 gene transcript levels were higher in nonpathogenic Leptospira-infected BMDMs than in pathogenic Leptospira-infected BMDMs at 24 h after infection (Table S4). This evidence concerns the gene CXCL1 and infection.
